Product Description:

The MDD093B-N-020-N2M-130PA1 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where a servo inverter supplies controlled three-phase current for precise rotary motion. In automated machinery, the motor can drive positioning tables, gantry axes, or tooling spindles that require repeatable velocity and torque. Its synchronous design supports accurate speed regulation during frequent starts, stops, and reversing moves. This operating profile fits production equipment that depends on steady axis response under changing load conditions.

The centering pilot has a diameter of 130 mm, which helps seat the motor concentrically in matching machine interfaces. Power and feedback cabling exit on Side A, which can simplify routing where space is limited near the non-drive end. Keeping the connections at one end can reduce cable crossover around adjacent machine hardware. Under continuous excitation, the motor delivers 14.5 Nm of standstill torque for feed axes that must resist static loads without overheating. The nominal speed is 2000 rpm, allowing the connected drive to operate within a predictable servo range. Frame size 093 gives the mounting dimensions and stator cross-section used for this motor size.

For power-off holding, the internal brake supplies 11 Nm of braking torque and can keep an axis from drifting at rest. Position feedback comes from an integrated multiturn absolute encoder, so the controller can retain position information after a shutdown. That feedback arrangement supports closed-loop positioning without a reference run after every restart. The motor uses a keyway shaft end for positive torque transmission to couplings or driven elements. It also has length code B, which indicates the housing length within this frame size. A shaft seal helps protect the bearing area from coolant splash and airborne contamination, and the housing uses standard balancing for smooth running at speed.
